YARN-CLEANING DEVICE.

Application filed Jul 17, 920. Serial no. 123,093.

This invention relates to yarn cleaning devices useful more particularly in connection with winding machinery to remove d1rt, loose lint, burs, slugs, surface knots, etc.,

5 from yarns, thereby to preclude imperfections in the fabrics subsequently knit or woven from such yarns.

In the usual types of winding machines, a great number of yarns are spooled at one time, thus necessitating employment of a .corresponding number of cleaning devices which require frequent attention to keep the yarn traversing slots free of accumulations tending to clog them. It is toward facilitat- 16 ing such cleaning and preventing unnecessary loss of time that my inventlon is in part directed, andthis desiderata I attain by provision of slug catcher blocks whlch are slidably retained under friction in hold-.

ers for convenience of ready and quick withdrawal without entailing com lete removal of the devices from the win ing machine.

The present invention is further concerned with structural improvements in the catcher blocks themselves, whereby they may be adapted to clean yarns of different gages.

, This end I secure by use, between two similar block components, of interchangeable shims, and by employment of suitable means to detachably secure the arts together.

With reference to the rawings herewith, Fig. I is a. perspective view of a yarn cleaning device conveniently embodymg my invention.

Fig. II ture showing Fig. III is a detail section taken as indicated by the arrows'III-III in Fig. II.

As herein depicted, the device comprises a bracket-like member 9 with a shank 10 whereby it may be' conveniently attached to the winding machine. The member 9 is furthermore formed with a head 12 which is recessed at 13 to serve as a holder for the slug catcher block comprehensively designated 14. This block 14 is slit longitudinally, as shown at 15, to provide the cleanin passa e or slot for traverse of the yarn in icated y the letter Y in Fig. I, said yarn being guided to a centralized position in the slot y eyes 16, 16 adjustably set in integral lugs 17, 17 above and below the hea r holder 12.

' frictional is a horizontal section of the structhe block and its holder; and

From Figs. 11 and III- it will be noted that the block 14 comprises two components 18, 19 which are exact duplicates, and which :are beveled as at 20, 20 to jointly provide an easy approach to the yarn traversing slot 15 for the purposes of ready threading. In accordance with my invention, the gage or width of the slot 15 is determined by a shim 21 interposed between -the component parts 18, 19 at one-end. As a convenient means to detachably secure the parts 18, 19 together, and to permit interchange of shims 21, I may employ screws 22 which pass through registeringclearing apertures in the component 18 and shim 21, and take into the component 19. With this arrangement, the block 14 may obviously be adapted for clean ing yarns of different ages, simply bysubstitution of shims 21 o proper thickness.

To determine its proper allocation in the holder 12, the block 14 is provided with integral longitudinally-flanking ridges 23, 23 designed to engage corresponding open grooves 24, 24 at opposite sides of the recess 13; and its retainment against dis lacement is insured by a bowed spring 25 w ich occupies one of the aforesaid slots 24, and exerts pressure upon the corresponding ridge 23 0 said block 14. The spring 25 is anchored at 26 in the member 9, and its free end is curled to the form of a loop 27 whereby it may be grasped by one hand for easement of the pressure u on the block 14 incidentallyto removal 0 the latter with the other hand.

By the described construction and arrangement it will be seenthat the blocks of a number ofsuch devices ma be quickly withdrawnand substitution e ected-without necessitating complete removal of such devices from the winding machine nor interfering with continuous operation of the latter.

Having thus described my invention, I claim:

1. A arn cleaning device comprising a bracketike member with arecessed head having opposed slots, a catcher-block embodying two similar component arts having flankin ridges adapted to shdingly fit the slots a oresaid, a shim interposed between the block components to determine the gigs of the cleaning slot, means securing the k components and shim rigidly together rid ges adapted able interchangeof shims and accommodation of the device to yarns of different gage, t e

and" flexible means co-operative with grooves to retain it against displacement.

2. A arn cleaning device comprising a bracketike' member with a recessed head having opposed co-planar slots at right angles thereto, a catcher-block embod mg two similar component parts having flan ing for sliding frictional fit in the head'slots aforesaid, a shim interposed between the block components to determine the gage of the cleaning slot, means securing adjacent flanking ridge gether with capacity for ready disassem ling to enable interchange of shims and accomow-spring reposing in one of the above named slots with its mner end anchored 1n the recessed head and its outer end formed into a ras loop, said sprin en a in the g of th% caiihirlock to eflectively retain the same against displacement.

Invtestimony whereof, I have hereunto signed my name at ,Lansdale, Pennsylvania, this 15th day of Jul 1926;
